Fire can transform even the most stubborn of objects. Bring on a little fire and blood with the Game of Thrones Targaryen Heat Sensitive Mug. The dark mug features the House Targaryen three-headed dragon sigil in vibrant red. Pour hot liquids into the mug and breath a little life into the design as the mug turns white and reveals the Targaryen motto of Fire and Blood.

Cup had huge flaw in dragon picture. Bubble from being made must have burst and caused a huge dent in the cup on the dragon picture. We didn't feel like waiting for a new one so now it's just another mug on the shelf...nothing special now.

This is a really cool mug....love how it changes but how it also tells me that my beverage is getting cold. Unfortunately, I cannot microwave nor put it in dishwasher. I really hate drinking out of hand washed mugs, not sanitary enough for me.It's a novelty for occasional use...not everyday.But it's a real show stopper!

I never had the opportunity to use the coffee cup because it was cracked when I pulled it out of the box. It was a slight crack so I didn't notice until I put coffee in it and it began leaking. I loved the cup, and would have used it frequently if that were possible.

I was really excited to get my mug in the mail. Unlike other "heat sensitive" mugs I have purchased in the past, this one really does change colors when hot liquid touches it--going from jet black to white. I use it for my morning hot water and lemon, hot coffee, cocoa. I don't have a dishwasher and I haven't tried to microwave anything in it so I can't comment as to those things. But it's really fun and would make a great gift for that Khaleesi or Targaryen in your life.

It tooks forever for this mug to be delievered to my house. Anyhow this mug is one of my faviorate mugs, It's so cool.I used it for drinking my breakfast tea, and any other time hot drinks. It turn white even if you washed it with a hot water. Its amazing.The only bad thing about it is that 11 ounces is the vol. for it which I knew about that before buying it so it was not a big deal, but It's totally worth the price.I highly recommended it.

I love this mug! It's a standard 8 oz. cup size, which is a bit small for me, but the novelty is worth it. I don't mind having to refill because the heat changing effect is SO COOL!

It is extremely reactive. This by far the best heat sensitive product that I've had. I have no issues with the fact that it needs hand washing, because even that is fun as the different water temperatures cool or heat the mug!

Both the Targaryen dragon sigil and their motto are very bold, clear images, you'll have no trouble making out what's on there.
